Which statement accurately describes a similarity between earth and venus?
a. both planets have an atmosphere primarily composed of oxygen.
b. both planets show evidence of volcanic activity.
c. both planets have retrograde rotation (clockwise, as viewed from above).
d. both planets contain liquid water at their surface.

B. Both planets show evidence of volcanic activity.

Explanation:

The Evidence of the volcanism in both the planets is a case and consequence of them being closely developed in the past and thus have the common characteristics of the volcanic activities in their geologic history and have a hot and active layer of the mantle. The surface comprised of 90% of the basalts and the 65% of the planet composed of the mosaic of the volcanoes and thus has a major role in forming the surface. The formation of these rocs about 2.5 bn years ago and the recent volcanic activity shows the presence of the more than 1000 volcanoes, which may have bee possible flooded by the lavas and an important component of the degassing. Shown by the presence of the creators and the volcanic hill mound and the zone of the methane gas flows.
